Hello to all!

Recently we faced some problem with UNISAB II.

Compressor with installed unit stopped within different
working time after start (2 minutes, 20 minutes, 1hour+ or even after 2hours)
there is no pattern or we do not see it ...

So, compressor is running and suddenly Unisab display went black
(like switched off) and within same second restart ... of course compressor
is stopped and must be restarted.

Strange thing is that we do not have any feedback alarm ...
not within UNISAB neither on PLC.

Maybe some of you faced similar problem with UNISAB II
and can give some useful advice ... the last exit is to contact SABROE,
but that is not easy because they forward those questions to nearest
representative .... and then .... not sure what

Thanks for your time and effort.

Best regards, Josip
